Il est connu de prévoir, à l'arrière ou sur les côtés d'un véhicule automobile, des dispositifs lumineux aptes à remplir différentes fonctions d'éclairage et de signalisation. Un projecteur comprenant des diodes électro-luminescentes (LED) disposées sur un circuit imprimé (PCB), lui-même assemblé à un support, est notamment connu du document CN203784789 .It is known to provide, at the rear or on the sides of a motor vehicle, light devices capable of performing different lighting and signaling functions. A headlamp comprising electroluminescent diodes (LEDs) arranged on a printed circuit board (PCB), itself assembled to a support, is notably known from the document CN203784789 .

L'assemblage du PCB avec le support est délicat pour des raisons d'ergonomie des pièces. En effet, les chocs lors de l'assemblage doivent être évités pour ne pas détériorer les LED, ou plus généralement les composants électroniques du PCB. Pour cette raison, l'assemblage du PCB avec le support nécessite en général des outils spécifiques et un procédé techniquement contraignant.The assembly of the PCB with the support is delicate for reasons of ergonomics of the parts. In fact, shocks during assembly must be avoided in order not to damage the LEDs, or more generally the electronic components of the PCB.

Les figures 1, 2 et 3 représentent un dispositif lumineux 10 selon un mode de réalisation de l'invention.The figures 1 , 2 and 3 represent a light device 10 according to one embodiment of the invention.

Le dispositif lumineux 10 comporte un circuit imprimé ou PCB 12 et un support 14, assemblés ou aptes à être assemblés l'un avec l'autre.The light device 10 comprises a printed circuit or PCB 12 and a support 14, assembled or able to be assembled with each other.

Le PCB 12 comporte une plaque 16 de substrat rigide, sur laquelle est déposé un matériau électriquement conducteur, formant un circuit électrique. La plaque 16 est sensiblement plane et comporte une première 18 et une seconde 20 faces opposées. Dans le mode de réalisation des figures 1 à 3, la plaque 16 a une forme essentiellement longitudinale, disposée selon un premier axe 22. En particulier, la plaque 16 comporte un premier 24 et un second 26 bords longitudinaux, situés de part et d'autre du premier axe 22.The PCB 12 comprises a plate 16 of rigid substrate, on which is deposited an electrically conductive material, forming an electrical circuit. The plate 16 is substantially flat and has a first 18 and a second 20 opposite faces. In the embodiment of Figures 1 to 3 , the plate 16 has a substantially longitudinal shape, arranged along a first axis 22. In particular, the plate 16 has a first 24 and a second 26 longitudinal edges, located on either side of the first axis 22.

Le PCB 12 comporte également des composants électroniques 28, fixés à la première face 18 de la plaque 16.The PCB 12 also comprises electronic components 28 fixed to the first face 18 of the plate 16.

Dans le mode de réalisation des figures 1 à 3, lesdits composants comprennent notamment des sources lumineuses 28 de type LED" visibles sur la figure 2 et par transparence sur la figure 1.In the embodiment of Figures 1 to 3 , said components include in particular light sources 28 of LED type "visible on the figure 2 and by transparency on the figure 1 .

Selon une variante non représentée, le dispositif lumineux 10 comporte au moins une source lumineuse fixée au support 14 et/ou à un autre élément de type radiateur. Dans ce cas, ladite source lumineuse est par exemple reliée électriquement au PCB 12 par l'intermédiaire d'un circuit imprimé flexible avant ou après assemblage du PCB 12 avec le support 14.According to a variant not shown, the light device 10 comprises at least one light source attached to the support 14 and / or to another radiator-type element. In this case, said light source is for example electrically connected to the PCB 12 via a flexible printed circuit before or after assembly of the PCB 12 with the support 14.

Le PCB 12 comporte également des éléments d'assemblage avec le support 14. Dans le mode de réalisation des figures 1 à 3, lesdits éléments d'assemblage sont formés par des découpes dans la plaque 16.The PCB 12 also includes connecting elements with the support 14. In the embodiment of the Figures 1 to 3 said connecting elements are formed by cutouts in the plate 16.

Un premier élément d'assemblage est formé par un trou traversant 30, proche d'une première extrémité de la plaque 16 selon l'axe 22. De préférence, le trou traversant 30 a une forme non symétrique selon un plan parallèle à l'axe 22 et perpendiculaire aux première 18 et seconde 20 faces. Dans le mode de réalisation des figures 1 à 3, le trou traversant 30 a une forme en demi-lune, avec un bord recourbé et un bord rectiligne respectivement disposés du côté du premier 24 et du second 26 bord longitudinaux de la plaque 16.A first connecting element is formed by a through hole 30, close to a first end of the plate 16 along the axis 22. Preferably, the through hole 30 has a non-symmetrical shape along a plane parallel to the axis 22 and perpendicular to the first 18 and second 20 faces. In the embodiment of Figures 1 to 3 the through hole 30 has a half-moon shape, with a curved edge and a straight edge respectively disposed on the side of the first longitudinal 24 and second 26 of the plate 16.

Un deuxième élément d'assemblage est formé par une première découpe 32, ménagée dans le premier bord longitudinal 24 de la plaque 16. La première découpe 32 est proche d'une seconde extrémité 33 de la plaque 16 selon l'axe 22.A second connecting element is formed by a first cut 32 formed in the first longitudinal edge 24 of the plate 16. The first cut 32 is close to a second end 33 of the plate 16 along the axis 22.

Un troisième élément d'assemblage est formé par une deuxième découpe 34, ménagée dans le second bord longitudinal 26 de la plaque 16. La deuxième découpe 34 est située entre le trou traversant 30 et la première découpe 32 selon l'axe 22.A third connecting element is formed by a second cutout 34, formed in the second longitudinal edge 26 of the plate 16. The second cutout 34 is located between the through hole 30 and the first cutout 32 along the axis 22.

Le support 14 est par exemple formé d'un ou de plusieurs matériaux plastiques. Le support 14 comporte par exemple une optique de sortie 36, destinée à faire partie d'une surface extérieure d'un véhicule automobile comprenant le dispositif lumineux 10.The support 14 is for example formed of one or more plastic materials. The support 14 comprises, for example, an output optic 36 intended to form part of an outer surface of a motor vehicle comprising the light device 10.

Le support 14 comporte également une partie de contact 37, adjacente à l'optique de sortie 36. Ladite partie de contact 37 est destinée à être au contact du PCB 12 lorsque ledit PCB est assemblé au support 14, comme sur la figure 3. Dans ladite partie de contact 37 sont ménagés des logements 38, destinés à être disposés en vis-à-vis des LED 28 du PCB 12. Entre lesdits logements 38 et l'optique de sortie 36, le support 14 comporte éventuellement des dispositifs optiques et/ou des guides lumineux supplémentaires (non représentés), destinés à transmettre et diffuser une lumière émise par les LED 28 vers l'extérieur du dispositif lumineux 10.The support 14 also has a contact portion 37, adjacent to the output optic 36. Said contact portion 37 is intended to be in contact with the PCB 12 when said PCB is assembled to the support 14, as on the figure 3 . In said contact portion 37 are provided housing 38, intended to be arranged vis-à-vis the LEDs 28 of the PCB 12. Between said housings 38 and the output optics 36, the support 14 optionally comprises optical devices and or additional light guides (not shown), intended to transmit and diffuse a light emitted by the LEDs 28 towards the outside of the light device 10.

Le support 14 comporte également des éléments de structure 40, destinés à l'assemblage dudit support 14 avec le véhicule automobile. Ces éléments de structure, ainsi que d'éventuelles pièces déjà assemblées au support 14, génèrent un encombrement spatial lors du montage du PCB 12 sur le support 14.The support 14 also comprises structural elements 40, intended for assembling said support 14 with the motor vehicle. These structural elements, as well as any parts already assembled to the support 14, generate a spatial space during the mounting of the PCB 12 on the support 14.

Dans la suite de la description, on considère une base orthonormée (X, Y, Z) définie par rapport au support 14. Dans le dispositif lumineux 10 en configuration assemblée, comme sur la figure 3, une direction principale d'émission de la lumière des LED 28 est parallèle à X. La direction Z correspond à la verticale, le dispositif lumineux 10 étant assemblé à un véhicule automobile.In the following description, we consider an orthonormal base (X, Y, Z) defined relative to the support 14. In the light device 10 in assembled configuration, as on the figure 3 , a main direction of emission of the LED light 28 is parallel to X. The Z direction corresponds to the vertical, the light device 10 being assembled to a motor vehicle.

Le support 14 comporte également des éléments d'assemblage avec le PCB 12, de sorte qu'en configuration assemblée (Figure 3), la plaque 16 soit sensiblement disposée contre la partie de contact 37 selon un plan (Y, Z), le premier axe 22 étant disposé selon Y.The support 14 also comprises assembly elements with the PCB 12, so that in assembled configuration ( Figure 3 ), the plate 16 is substantially disposed against the contact portion 37 in a plane (Y, Z), the first axis 22 being arranged along Y.

Un premier élément d'assemblage du support 14 avec le PCB 12 est formé par une tige pivot 42. En particulier, la tige pivot 42 est destinée à être assemblée au trou traversant 30 du PCB 12 et à coopérer avec ledit trou traversant.A first connecting element of the support 14 with the PCB 12 is formed by a pivot rod 42. In particular, the pivot rod 42 is intended to be assembled to the through hole 30 of the PCB 12 and to cooperate with said through hole.

La tige pivot 42 a une forme sensiblement longitudinale, disposée selon un deuxième axe 44 parallèle à X. La tige pivot 42 forme une saillie par rapport à la partie de contact 37 du support 14. Ladite saillie est orientée vers l'arrière, soit dans le sens opposé à l'optique de sortie 36.The pivot rod 42 has a substantially longitudinal shape, disposed along a second axis 44 parallel to X. The pivot rod 42 forms a projection relative to the contact portion 37 of the support 14. Said projection is oriented towards the rear, or in the opposite direction to the output optics 36.

Une première extrémité de la tige pivot 42, reliée à la partie de contact 37, est formée par une butée axiale 45. Une seconde extrémité, libre, de ladite tige pivot 42 est formée par un bouton d'introduction 46.A first end of the pivot rod 42, connected to the contact portion 37, is formed by an axial stop 45. A free second end of said pivot rod 42 is formed by an insertion button 46.

Sur la figure 1, le PCB 12 est dans une configuration d'emboîtement du trou traversant 30 avec le bouton d'introduction 46, permettant d'enfiler le PCB 12 sur la tige pivot 42. Dans cette configuration d'emboîtement, la plaque 16 est sensiblement disposée perpendiculaire au deuxième axe 44. La première face 18 de ladite plaque 16 est orientée vers la partie de contact 37 du support 14, soit vers l'avant sur les figures.On the figure 1 , the PCB 12 is in an interlocking configuration of the through-hole 30 with the insertion button 46, allowing the PCB 12 to be threaded onto the pivot rod 42. In this interlocking configuration, the plate 16 is substantially perpendicularly disposed. to the second axis 44. The first face 18 of said plate 16 is oriented towards the contact portion 37 of the support 14, or forwards in the figures.

Dans la configuration d'emboîtement, le premier axe 22 forme un angle a (Figure 3) avec la position dudit axe 22 en configuration assemblée. De préférence, l'angle a est supérieur ou égal à 45°.In the interlocking configuration, the first axis 22 forms an angle α ( Figure 3 ) with the position of said axis 22 in assembled configuration. Preferably, the angle a is greater than or equal to 45 °.

Dans le mode de réalisation des figures 1 à 3, l'angle a est sensiblement égal à 90°. Dans la configuration d'emboîtement, le premier axe 22 est disposé selon Z et la seconde extrémité 33 de la plaque 16 est orientée vers le bas.In the embodiment of Figures 1 to 3 the angle a is substantially equal to 90 °. In the interlocking configuration, the first axis 22 is disposed along Z and the second end 33 of the plate 16 is oriented downwards.

Une section transversale dudit bouton d'introduction 46 a une forme sensiblement complémentaire de celle du trou traversant 30 du PCB 12, dans ladite configuration d'emboîtement. En revanche, lorsque l'axe 22 de la plaque 16 est incliné par rapport à sa position verticale de la figure 1, la forme du bouton d'introduction 46 n'est plus complémentaire de celle du trou traversant 30. Le bouton d'introduction 46 forme alors une butée empêchant de séparer le PCB 12 de la tige pivot 42 par translation selon l'axe 44.A cross section of said insertion button 46 has a shape substantially complementary to that of the through hole 30 of the PCB 12, in said configuration nesting. On the other hand, when the axis 22 of the plate 16 is inclined with respect to its vertical position of the figure 1 , the shape of the insertion button 46 is no longer complementary to that of the through hole 30. The introduction button 46 then forms a stop preventing separation of the PCB 12 from the pivot rod 42 by translation along the axis 44.

Dans le mode de réalisation des figures 1 à 3, le bouton d'introduction 46 du support 14 a une forme en demi-lune, symétrique selon un plan (X, Y).In the embodiment of Figures 1 to 3 , the introduction button 46 of the support 14 has a half moon shape, symmetrical in a plane (X, Y).

Entre la butée axiale 45 et le bouton d'introduction 46, la tige pivot 42 comporte une portion de rotation 50. Une longueur axiale de la portion de rotation 50 autorise au PCB 12 un jeu en translation selon l'axe 44, entre les butées 45 et 46.Between the axial abutment 45 and the insertion button 46, the pivot rod 42 comprises a rotational portion 50. An axial length of the rotational portion 50 allows the PCB 12 a translational clearance along the axis 44, between the stops 45 and 46.

Par ailleurs, les dimensions transversales de la portion de rotation 50 sont inférieures à celles du bouton d'introduction 46. En particulier, lorsque le trou traversant 30 du PCB 12 est enfilé sur ladite portion de rotation 50, ledit PCB 12 est apte à pivoter autour du deuxième axe 44 parallèle à X.Moreover, the transverse dimensions of the rotational portion 50 are smaller than those of the insertion button 46. In particular, when the through hole 30 of the PCB 12 is threaded onto said rotational portion 50, said PCB 12 is able to rotate around the second axis 44 parallel to X.

En outre, la forme et les dimensions du trou traversant 30 et de la tige pivot 42 permettent au PCB 12, enfilé sur la portion de rotation 50, de pivoter autour d'au moins un axe perpendiculaire au deuxième axe 44. Dans le mode de réalisation des figures 1 à 3, le PCB 12, enfilé sur la portion de rotation 50, peut pivoter autour de tout axe compris dans un plan (Y, Z) passant par la portion de rotation 50.In addition, the shape and dimensions of the through hole 30 and the pivot rod 42 allow the PCB 12, threaded on the rotational portion 50, to pivot about at least one axis perpendicular to the second axis 44. realization of Figures 1 to 3 , the PCB 12, threaded on the rotational portion 50, is pivotable about any axis included in a plane (Y, Z) passing through the rotational portion 50.

En particulier, le PCB 12, enfilé sur la portion de rotation 50, peut pivoter perpendiculairement à X, de sorte à déplacer vers l'arrière la seconde extrémité 33 de la plaque 16.In particular, the PCB 12, threaded on the rotational portion 50, can pivot perpendicularly to X, so as to rearwardly move the second end 33 of the plate 16.

La forme des premiers éléments d'assemblage permet aux mouvements de rotation du PCB 12, autour de X et perpendiculairement à X, d'avoir lieu simultanément ou séparément. L'amplitude de rotation du PCB 12 autour d'un axe perpendiculaire à X dépend d'une position angulaire dudit PCB 12 par rapport à X.The shape of the first assembly elements allows the rotational movements of the PCB 12, around X and perpendicular to X, to take place simultaneously or separately. The amplitude of rotation of the PCB 12 about an axis perpendicular to X depends on an angular position of said PCB 12 with respect to X.

Sur la figure 2, le PCB 12 est représenté dans une configuration intermédiaire d'assemblage, le premier axe 22 étant disposé dans le même plan (X, Y) que dans la configuration assemblée de la figure 3. Dans cette configuration intermédiaire d'assemblage, le premier axe 22 est apte à former un angle maximal β avec la position dudit axe 22 en configuration assemblée. L'angle maximal β correspond à un débattement maximal vers l'arrière de la seconde extrémité 33 de la plaque 16, par rapport à la partie de contact 37.On the figure 2 , the PCB 12 is shown in an intermediate assembly configuration, the first axis 22 being arranged in the same plane (X, Y) as in the assembled configuration of the figure 3 . In this intermediate assembly configuration, the first axis 22 is able to form a maximum angle β with the position of said axis 22 in assembled configuration. The maximum angle β corresponds to a maximum deflection towards the rear of the second end 33 of the plate 16, with respect to the contact part 37.

De préférence, l'angle maximal β est compris entre 5° et 25°, plus préférentiellement égal à environ 20°.Preferably, the maximum angle β is between 5 ° and 25 °, more preferably equal to about 20 °.

Un deuxième élément d'assemblage du support 14 avec le PCB 12 est formé par une encoche 54, apte à être assemblée à la première découpe 32 dudit PCB 12.A second assembly element of the support 14 with the PCB 12 is formed by a notch 54, able to be assembled at the first cut 32 of said PCB 12.

L'encoche 54 s'étend sensiblement selon Y et est ménagée dans un taquet 56 relié à la partie de contact 37 du support 14. Le taquet 56 est sensiblement disposé selon X et orienté vers l'arrière.The notch 54 extends substantially along Y and is formed in a catch 56 connected to the contact portion 37 of the support 14. The stopper 56 is substantially arranged along X and facing rearwardly.

Selon X, l'encoche 54 est délimitée d'une part par une butée 58, orientée vers la partie de contact 37, et d'autre part par un bourrelet 60 formant une extrémité libre du taquet 56. Selon Z, l'encoche 54 est ménagée sur une partie supérieure du taquet 56.According to X, the notch 54 is delimited on the one hand by a stop 58, oriented towards the contact portion 37, and on the other hand by a bead 60 forming a free end of the catch 56. According to Z, the notch 54 is formed on an upper part of the cleat 56.

Dans la configuration assemblée de la figure 3, la première découpe 32 du PCB 12 est insérée dans l'encoche 54. La plaque 16 est ainsi bloquée en rotation autour du deuxième axe 44, dans le sens qui tendrait à ramener vers le bas la seconde extrémité 33 de ladite plaque 16.In the assembled configuration of the figure 3 , the first cut 32 of the PCB 12 is inserted in the notch 54. The plate 16 is thus locked in rotation about the second axis 44, in the direction tending to bring down the second end 33 of said plate 16.

Un troisième élément d'assemblage du support 14 avec le PCB 12 permet de bloquer la plaque 16 dans le sens de rotation opposé, en coopérant avec la deuxième découpe 34 dudit PCB 12.A third connection element of the support 14 with the PCB 12 makes it possible to block the plate 16 in the opposite direction of rotation, by cooperating with the second cutout 34 of said PCB 12.

Ledit troisième élément d'assemblage est formé par une languette 62, en relief selon X par rapport à la partie de contact 37 du support 14, et orientée vers l'arrière. La languette 62 comporte notamment une extrémité libre 64 selon X.Said third assembly element is formed by a tongue 62, raised in X relative to the contact portion 37 of the support 14, and oriented towards the rear. The tongue 62 comprises in particular a free end 64 along X.

Une partie inférieure de ladite languette 62 comporte une cavité 66, disposée à l'écart de l'extrémité libre 64. Ladite cavité 66 a une forme complémentaire de celle de la deuxième découpe 34, de sorte à bloquer la plaque 16 en rotation et en translation selon le deuxième axe 44.A lower part of said tongue 62 has a cavity 66 disposed away from the free end 64. Said cavity 66 has a shape complementary to that of the second cutout 34, so as to block the plate 16 in rotation and in rotation. translation along the second axis 44.

Dans le mode de réalisation des figures 1 à 3, la languette 62 est flexible et apte à se déformer élastiquement par torsion autour d'un axe parallèle à Y ; de plus, la cavité 66 est traversante selon Z.In the embodiment of Figures 1 to 3 the tongue 62 is flexible and able to deform elastically by torsion around an axis parallel to Y; in addition, the cavity 66 is through Z.

Selon une variante de réalisation non représentée, la languette 62 est fixée à la partie de contact 37 à la fin du procédé d'assemblage du support 14 avec le PCB 12. Selon cette variante, la languette 62 peut être rigide et/ou la cavité 66 peut être non traversante.According to an alternative embodiment not shown, the tongue 62 is fixed to the contact portion 37 at the end of the assembly process of the support 14 with the PCB 12. According to this variant, the tongue 62 may be rigid and / or the cavity 66 may be non-traversing.

Un procédé d'assemblage du dispositif lumineux 10 va maintenant être décrit. Par rapport au support 14, le PCB 12 est placé dans la configuration d'emboîtement représentée à la figure 1. Le trou traversant 30 de la plaque 16 est ensuite enfilé sur la tige pivot 42.A method of assembling the light device 10 will now be described. With respect to the support 14, the PCB 12 is placed in the interlocking configuration shown in FIG. figure 1 . The through hole 30 of the plate 16 is then threaded onto the pivot rod 42.

Les formes particulières du trou traversant 30 et du bouton d'introduction 46 ont une fonction de détrompage, de sorte que les LED 28 sont nécessairement orientées vers la partie de contact 37 du support 14.The particular shapes of the through hole 30 and the insertion button 46 have a polarizing function, so that the LEDs 28 are necessarily oriented towards the contact portion 37 of the support 14.

Le PCB 12 est translaté selon le deuxième axe 44 jusqu'à être bloqué par la butée axiale 45 de la tige pivot 42. Le trou traversant 30 est alors disposé autour de la portion de rotation 50 de ladite tige pivot 42.The PCB 12 is translated along the second axis 44 until it is blocked by the axial stop 45 of the pivot rod 42. The through hole 30 is then arranged around the rotational portion 50 of said pivot rod 42.

Un premier mouvement de rotation est alors appliqué au PCB 12 de sorte à déplacer vers l'arrière la seconde extrémité 33 de la plaque 16. Le premier mouvement de rotation a lieu autour d'un axe perpendiculaire à X.A first rotational movement is then applied to the PCB 12 so as to rearwardly move the second end 33 of the plate 16. The first rotational movement takes place about an axis perpendicular to X.

Simultanément ou suite audit premier mouvement, un deuxième mouvement de rotation est appliqué au PCB 12 autour du deuxième axe 44, de sorte à déplacer vers le haut la seconde extrémité 33 de la plaque 16. Le PCB 12 arrive ainsi à la configuration intermédiaire d'assemblage de la figure 2. L'angle β de débattement vers l'arrière permet à ladite seconde extrémité 33 de passer à l'écart du bourrelet 60 alors que le deuxième mouvement de rotation se poursuit. La plaque 16 ne vient donc pas en butée contre le taquet 56 durant ledit deuxième mouvement.Simultaneously or following said first movement, a second rotational movement is applied to the PCB 12 about the second axis 44, so as to move up the second end 33 of the plate 16. The PCB 12 thus arrives at the intermediate configuration of assembly of the figure 2 . The backward deflection angle β allows said second end 33 to pass away from the bead 60 while the second rotational movement continues. The plate 16 does not come into abutment against the latch 56 during said second movement.

Le deuxième mouvement de rotation autour de l'axe 44 est poursuivi jusqu'à ce que la première découpe 32 soit située plus haut que le taquet 56 par rapport à Z.The second rotational movement about the axis 44 is continued until the first cut 32 is located higher than the stop 56 with respect to Z.

Un troisième mouvement de rotation est alors appliqué au PCB 12 de sorte à déplacer vers l'avant la seconde extrémité 33 de la plaque 16. Le troisième mouvement de rotation a lieu autour d'un axe perpendiculaire à X. La plaque 16 est ainsi rabattue vers la partie de contact 37 du support 14, de manière inverse au premier mouvement de rotation.A third rotational movement is then applied to the PCB 12 so as to move forward the second end 33 of the plate 16. The third rotational movement takes place about an axis perpendicular to X. The plate 16 is thus folded towards the contact portion 37 of the support 14, in a manner opposite to the first rotational movement.

Le troisième mouvement de rotation est poursuivi jusqu'à ce que le premier axe 22 se trouve dans un même plan (Y, Z) que dans la configuration assemblée de la figure 3. La première découpe 32 du PCB 12 est alors située au-dessus de l'encoche 54 du taquet 56.The third rotational movement is continued until the first axis 22 is in the same plane (Y, Z) as in the assembled configuration of the figure 3 . The first cut 32 of the PCB 12 is then located above the notch 54 of the stopper 56.

Un quatrième mouvement de rotation est alors appliqué au PCB 12 autour du deuxième axe 44, de sorte à déplacer vers le bas la seconde extrémité 33 de la plaque 16. La première découpe 32 est ainsi abaissée de sorte à s'insérer dans l'encoche 54.A fourth rotational movement is then applied to the PCB 12 around the second axis 44, so as to move the second end 33 of the plate 16 downwards. The first cut 32 is thus lowered so as to fit into the notch 54.

Le PCB 12 et le support 14 sont alors dans la configuration assemblée de la figure 3, formant le dispositif lumineux 10. Les LED 28 du PCB 12 sont disposés en vis-à-vis des logements 38 de la partie de contact 37 du support 14, de sorte à diffuser de la lumière vers l'optique de sortie 36.The PCB 12 and the support 14 are then in the assembled configuration of the figure 3 forming the light device 10. The LEDs 28 of the PCB 12 are arranged facing the housings 38 of the contact portion 37 of the support 14, so as to diffuse light towards the output optics 36.

L'insertion de la première découpe 32 dans l'encoche 54 bloque le PCB 12 en rotation autour de l'axe 44, par rapport au support 14, dans un premier sens de rotation. Cette insertion bloque également le PCB 12 en translation selon X, ainsi qu'en rotation autour de Y et de Z.The insertion of the first cutout 32 in the notch 54 blocks the PCB 12 in rotation about the axis 44, relative to the support 14, in a first direction of rotation. This insertion also blocks the PCB 12 in translation along X, and in rotation around Y and Z.

De plus, en configuration assemblée, la portion de rotation 50 dans le trou traversant 30 bloque le PCB 12 en translation selon Y par rapport au support 14.In addition, in assembled configuration, the rotational portion 50 in the through hole 30 blocks the PCB 12 in translation along Y relative to the support 14.

Dans la configuration intermédiaire d'assemblage de la figure 2, durant le deuxième mouvement de rotation selon l'axe 44, le second bord longitudinal 26 de la plaque 16 arrive en butée contre l'extrémité libre 64 de la languette 62. Lorsque le deuxième mouvement de rotation se poursuit pour faire passer la première découpe 32 au-dessus du taquet 56, la pression de la plaque 16 déforme la languette 62 vers le haut. Ensuite, lorsque la première découpe 32 est insérée dans l'encoche 54, la deuxième découpe 34 dudit deuxième bord longitudinal 26 s'insère dans la cavité 66 de la languette 62, ladite languette reprenant sa forme initiale.In the intermediate assembly configuration of the figure 2 during the second rotational movement along the axis 44, the second longitudinal edge 26 of the plate 16 comes into abutment against the free end 64 of the tongue 62. When the second rotational movement continues to pass the first cut 32 above the tab 56, the pressure of the plate 16 deforms the tab 62 upwards. Then, when the first blank 32 is inserted into the notch 54, the second blank 34 of said second longitudinal edge 26 is inserted into the cavity 66 of the tongue 62, said tongue returning to its original shape.

L'insertion de la deuxième découpe 34 dans la cavité 66 bloque le PCB 12 en rotation autour de X, dans un second sens de rotation. Chacun des deuxième 32, 54 et troisième 34, 66 éléments d'assemblage du PCB 12 et du support 14 bloque donc ledit PCB 12 par rapport audit support 14 selon un sens différent de rotation selon X.The insertion of the second cutout 34 into the cavity 66 blocks the PCB 12 rotating around X in a second direction of rotation. Each of the second 32, 54 and third 34, 66 assembly elements of the PCB 12 and the support 14 thus blocks said PCB 12 relative to said support 14 in a different direction of rotation along X.

De manière optionnelle, l'insertion de la deuxième découpe 34 dans la cavité 66 bloque également le PCB 12 par rapport au support 14, en translation selon X et/ou selon Y, et/ou en rotation autour de Z.Optionally, the insertion of the second cutout 34 into the cavity 66 also blocks the PCB 12 relative to the support 14, in translation along X and / or along Y, and / or in rotation around Z.

Selon la variante de réalisation précédemment évoquée, la languette 62 est fixée à la partie de contact 37 du support 14 après l'insertion de la première découpe 32 dans l'encoche 54, de sorte à bloquer le PCB 12 dans le second sens de rotation. La fixation de la languette 62 au support 14 est par exemple effectuée par clipsage ou vissage.According to the previously mentioned embodiment variant, the tongue 62 is fixed to the contact portion 37 of the support 14 after the insertion of the first cutout 32 in the notch 54, so as to block the PCB 12 in the second direction of rotation . Fixing the tongue 62 to the support 14 is for example made by clipping or screwing.

Le procédé d'assemblage décrit ci-dessus nécessite une amplitude de mouvement relativement faible, notamment en ce qui concerne les rotations du PCB 12. Ce dernier peut ainsi être assemblé au support 14 même dans le cas où ledit support est placé dans un environnement déjà encombré.The assembly method described above requires a relatively small amplitude of movement, especially with regard to the rotations of the PCB 12. The latter can thus be assembled to the support 14 even if said support is placed in an environment already crowded.

Par ailleurs, l'assemblage peut être effectué à la main par un opérateur, sans outil spécifique et sans que le PCB 12 ne subisse de chocs nuisibles aux composants électroniques, notamment aux LED 28.Moreover, the assembly can be carried out by hand by an operator, without specific tools and without the PCB 12 suffering damaging shocks to electronic components, including LEDs 28.

Le PCB 12 en configuration assemblée est entièrement bloqué en rotation et translation par rapport au support 14, de manière à rester au contact dudit support en cas de vibrations du véhicule équipé du dispositif lumineux 10.The PCB 12 in assembled configuration is completely locked in rotation and translation relative to the support 14, so as to remain in contact with said support in case of vibrations of the vehicle equipped with the light device 10.
